I am probably gonna get a 120gb HD this summer, and according to my friend it's alot harder to format it and everything if I have a soft mod (which I have now) and that a chip is alot faster. Mainly for this reason I wanna get a chip in my Xbox, but I wanna get on with a switch that I can install in the back to turn it on or off, so I can go on live. I would prefer a pretty cheap chip too, so, what chip do you guys think I should get?
